I purchased this shed because it is constructed and made out of the same material as another shed that I have had for several years to house my grill. Since it has stood the test of several winters and summers, I decided to get this shed for my gardening equipment. I am very pleased with it. My wife and I put this together in less than 2 hours. The pieces are clearly marked and the instructions are very thorough. Note that I did not say they were easy to follow. That characteristic will depend on the person putting this together. I can usually look at the pieces of a product and figure out in my head how they go together. If you are that kind of person, then this is going to be easy. If you are not that kind of person, you may or may not have trouble with this. The pictures are for the most part very clear. The instructions go into detail about what you should do with each piece to snap or screw them together. The pieces go together easily if you follow the instructions correctly. I am very happy with a product when the slots and the holes line up like they are supposed to. This product was great in that area. The only two somewhat difficult items were one of the roof supports and the door hinges. The instructions for the thin roof support is very specific about showing you how to orient the piece in the roof, but the arrow pointing to the spot on the roof is not as precise. It is hard to tell if the piece goes on the outside of the roof or in a slot in the roof. I put it on the outside, but was not satisfied with that decision because there were no indentations for the screws on the outside. Then my wife and I saw a slot in the roof that had the screw hole indentations. Then we installed it correctly. As for the hinges, the instructions are again very specific about how they go. But I thought that I would be screwing the hinges into the fame of the shed and so I though the picture was backwards. But the picture was correct and when I finally put the hinges on the door in the correct way, I saw that the hinges fit into grooves in the shed and the screws you use screw into threaded holes in the hinges and as you tighten the screw it causes the hinges to clamp down on the frame and secure the hinges. The are two small holes in the top back of the shed. They may be for air circulation, but I put flex-tape over them because someone complained about water getting into the shed when it rained. If you construct this shed on a flat level surface, the floor is considerable strong and the parts fit correctly. I would not roll a 300lb air compressor over the floor, but it will easily support my push lawnmower. I think this is a quality product for the purpose for which I want it. If after a winter and summer I see some failure, I will update this review. But for now, I am very pleased with it.
